If you're looking for the Japanese equivalent of the BMW M5, the 2015 Lexus GS F would be it. Leaked images now reveal that it will come with a 5.0-liter naturally aspirated V8 producing 465 horsepower. If it's also lighter than the German competition, we might be in for a blast.

As you can see in scans from this Japanese magazine (that appear to have been shot in Los Angeles), the GS F has air intakes and a sporty carbon fiber body kit makes sure you get the picture at the red light, while the V8's sound rumbles through the now signature stacked double exhausts seen on the Lexus IS F before it.

But will this be enough for those looking for an alternative super sedan other than a Jaguar?
